The Universal Cloud and Aerosol Sounding System (UCASS): a low-cost miniature optical particle counter for use in dropsonde or balloon-borne sounding systems
(2019-12-13)
A low-cost miniaturized particle counter has been developed by The University of Hertfordshire (UH) for the measurement of aerosol and droplet concentrations and size distributions. The Universal Cloud and Aerosol Sounding ...
AIITS: Preliminary light scattering data from Tropical Tropopause Layer cirrus
(2015-07-22)
The new optical particle spectrometer AIITS (Aerosol Ice Interface Transition Spectrometer) is the next instrument in the Small Ice Detector (SID) family. Like SID3, it acquires two-dimensional forward scattering patterns ...
Incidence of rough and irregular atmospheric ice particles from Small Ice Detector 3 measurements
(2014-02-12)
The knowledge of properties of ice crystals such as size, shape, concavity and roughness is critical in the context of radiative properties of ice and mixed-phase clouds. Limitations of current cloud probes to measure these ...
The effective density of small ice particles obtained from in situ aircraft observations of mid-latitude cirrus
(2013-10)
The effective ice-particle density, parametrized through a mass–dimension relation, is widely used in ice microphysical schemes for weather and climate models. In this study, we use aircraft-based observations in mid-latitude ...
Miniature, low-cost optical particle counters
(2013)
A range of miniature, low-cost optical particle counters for characterizing atmospheric particles has been developed. They are intended for use with disposable balloon-borne radiosondes, dropsondes or in dense ground-based ...
Radiosonde aerosol counter for vertical profiling of atmospheric dust
(2010)
A low-cost, miniature aerosol particle counter has been developed, intended for use with balloon-borne meteorological radiosondes. It is particularly suitable for airborne mineral dust measurements. Ambient air is drawn ...
Atmospheric dust charging, vertical profiles, and optical properties measured in the Arabian Peninsula during the DREAME campaign
(2010)
Polarimetric observations of atmospheric Saharan dust over the Canary Islands have provided strong evidence for the presence of vertically aligned particles. The alignment was thought to be due to the electric field present ...
